In Juneau, surrounded by miles of ice and wilderness, we tend to depend on certain constants, familiar elements that add to our definition of home. The mist on the mountains. Folk fest. Jeff Brown. Even if you’ve never met Brown in person, you’ve likely come into contact with him in one way or another. Maybe his voice has kept you company on your drive home from work. Maybe you’ve laughed out loud at his magazine, “Real Alaskan,” and photo exhibits. Or maybe your kids have been among the throngs he’s delighted at parties, libraries and on street corners.
